Abstract: Circuits and computer program products onboard and/or adapted to communicate with an scanner that electronically recognize predefined physical characteristics of the at least one tool to automatically segment image data provided by the scanner whereby the at least one tool constitutes a point of interface with the system. The circuits and computer program products are configured to provide a User Interface that defines workflow progression for an image guided surgical procedure and allows a user to select steps in the workflow, and generate multi-dimensional visualizations using the predefined data of the at least one tool and data from images of the patient in substantially real time during the surgical procedure.

Abstract: A trajectory frame for use with surgical navigation systems includes a base having a patient access aperture formed therein. A yoke is mounted to the base and is rotatable about a roll axis. A platform is mounted to the yoke and is rotatable about a pitch axis. An elongated guide is secured to the platform and includes opposite proximal and distal end portions and a bore that extends from the proximal end portion to the distal end portion. The guide is configured to removably receive various devices therein for quick release therefrom, including an optical tracking probe (which may be a universal tracker) detectable by a camera-based tracking system or an EM probe detectable by an EM navigation system, a microelectrode probe driver adapter, a drill guide and drill bit, skull fixation device and driver, and a catheter guide.

Abstract: Fiber optic systems with an MR compatible mouse in an MR scanner room that connects to a fiber optic computer mouse interface that is attached to a fiber optic cable that connects to a USB port of a computer in the MR control room to allow the mouse in the MR scanner room to move a cursor on a monitor in communication with the computer in the control room of an MRI suite during an MRI guided surgical procedure. The fiber optic cable(s) can be routed though a conventional RF wall waveguide and avoids the need for additional holes in the penetration panel for connectors. The fiber optic systems can also include up converters and down converters for providing fiber optic video signals from cameras in the MR scanner room to display video signal on the monitor.

Abstract: An MRI-compatible base is configured to support an MRI-compatible head support frame. The base is configured to be secured to a gantry associated with an MRI scanner, and to extend across a width of the gantry. The base allows the head support frame to be moved to any of a plurality of locations across the width of the gantry, and allows the head support frame to rotate about two orthogonal axes so as to be positioned at any of a plurality of angles relative to the gantry.

Abstract: An MRI-compatible catheter that reduces localized heating due to MR scanner-induced currents includes an elongated flexible shaft having a distal end portion and an opposite proximal end portion. A handle is attached to the proximal end portion and includes an electrical connector interface configured to be in electrical communication with an MRI scanner. One or more RF tracking coils are positioned adjacent the distal end portion of the shaft. Each RF tracking coil includes a conductive lead, such as a coaxial cable, that extends between the RF tracking coil and the electrical connector interface and electrically connects the RF tracking coil to an MRI scanner. In some embodiments of the present invention, the conductive lead has a length sufficient to define an odd harmonic/multiple of a quarter wavelength of the operational frequency of the MRI Scanner, and/or includes a series of pre-formed back and forth segments along its length.
